Background
The South Coast Botanic Garden is the first botanic garden in the world to be built on a sanitary landfill. Prior to its landfill
use, the Great Lakes Carbon Company mined the 87 acre site for diatomaceous earth. The property was purchased in 1956 by Los
Angeles County as one of the County's first sanitary landfills to meet the County's growing landfill needs. At the request
of residents headed by Francis Young, the Los Angeles County Board of Supervisors approved converting the landfill to a garden
in 1960, with plantings beginning in 1961. The South Coast Botanic Garden was recognized by the California Mining Association
in 1990 with its first Excellence in Reclamation award for "signifcant achievement in planning, practice and environmental
protection."
